Model 466-1 Adapter
50 CSR Accessed From The SBus
INTERRUPT PENDING (bit 4): Set to "1" when the adapter is generating an
interrupt. When polling to determine if the adapter is causing an interrupt, bit
4 is the only register bit that needs to be checked.
LATCHED CINT4 (bit 3): Set to "1" when the adapter is receiving a cable
interrupt on CINT4.
LATCHED CINT3 (bit 2): Set to "1" when the adapter is receiving a cable
interrupt on CINT3.
LATCHED CINT2 (bit 1): Set to "1" when the adapter is receiving a cable
interrupt on CINT2.
LATCHED CINT1 (bit 0): Set to "1" when the adapter is receiving a cable
interrupt on CINT1.
Cable interrupt sources (CINT4 - CINT1) are configured on the VMEbus
adapter card using the
T-INT jumper block; see section 4.5.
6.2 Remote Node Registers
Eight adapter remote node registers are controlled by processors on the SBus
chassis but are located on the
remote (VMEbus) adapter card.
